PHP - Auto Link Function Problem
I found a function online to auto link any variable containing text. It looks for http:// or www. in the text and then automatically adds the HTML code to turn it into a link. I have a problem though.. I have some html already in some of the variables that contain IMG tags. This function tries to link the url of the image.. so I get something like this:
Code: [Select] <img src="<a rel="nofollow" href="IMAGEURL" target="_blank">IMAGEURL</a>" border="0" /> This creates a problem and the images don't load! Is there anyway to stop it from doing this? function auto_link($text) { $pattern = '#\b(([\w-]+://?|www[.])[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/)))#'; return preg_replace_callback($pattern, 'auto_link_callback', $text); } function auto_link_callback($matches) { $max_url_length = 50; $max_depth_if_over_length = 2; $ellipsis = '…'; $url_full = $matches[0]; $url_short = ''; if (strlen($url_full) > $max_url_length) { $parts = parse_url($url_full); $url_short = $parts['scheme'] . '://' . preg_replace('/^www\./', '', $parts['host']) . '/'; $path_components = explode('/', trim($parts['path'], '/')); foreach ($path_components as $dir) { $url_string_components[] = $dir . '/'; } if (!empty($parts['query'])) { $url_string_components[] = '?' . $parts['query']; } if (!empty($parts['fragment'])) { $url_string_components[] = '#' . $parts['fragment']; } for ($k = 0; $k < count($url_string_components); $k++) { $curr_component = $url_string_components[$k]; if ($k >= $max_depth_if_over_length || strlen($url_short) + strlen($curr_component) > $max_url_length) { if ($k == 0 && strlen($url_short) < $max_url_length) { // Always show a portion of first directory $url_short .= substr($curr_component, 0, $max_url_length - strlen($url_short)); } $url_short .= $ellipsis; break; } $url_short .= $curr_component; } } else { $url_short = $url_full; } return "<a rel=\"nofollow\" href=\"$url_full\" target=\"_blank\">$url_short</a>"; } Similar Tutorialsplease this code is not working,i want when users comment on a page it should refresh this is my code: Code: [Select] <h3>Comments:</h3> <table> <tr class="row-a"> <td class="first"></td> <td><?php include"header.php"; $sql="SELECT post_content,post_by FROM post ORDER BY topicsID"; $result=mysql_query($sql)or die(mysql_error()); while($row=mysql_fetch_array($result)) { echo"<strong>{$row['post_by']}</strong>: {$row['post_content']}"."</br>"; } if(mysql_affected_rows()>0) { header("location:".$_SERVER['PHP_SELF']); } ?></td> </tr> </table> <h3>Post your comments here</h3> <form action='reply.php'method='post'> <textarea name="comment" id="content" style="width:400px;height:50px;background-color:#D0F18F;color:#000000;font:15px/20px cursive;scrollbar-base-color:#638E0D;"></textarea> <br /> Name:<input type="text"name="name"/> <input class="button" type="submit"name="submit"value="submit" /> </p> </form> <br /> [code] In a script links are captured from the internet by $link, then display it by echo $link The links have the general format of http://domain.com/something/filename.html I am looking for a simple way to display capture some elements from $link and display "domain.com" and "filename" In other words, I need a code to remove other parts of the link provided by $link I have a feeling someone is going to say AJAX but here goes, Currently I have a basic php / html page the goes something like this: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>BASIC HTML PAGE</title> </head> <body> <?php include 'home.inc.php'; ?> </body> </html> Now I've added some links: Code: [Select] <li><a href="#">Add</a></li> What I'm after is when someone click on that link is it changes the <?php include 'home.inc.php'; ?> From the base file to <?php include 'add.inc.php'; ?> Help much appreciated! I have a page which reads content from a database and display its result.
<?php
include ("databaseconnections/conx_stampsforsale.php");
$sql = mysql_query("SELECT country, description, price FROM stampsforsale");
if (!$sql)
die ("Error Displaying Data. " . mysql_error());
else
{
echo ("<table><tr>");
$count = 0;
while ($row = mysql_fetch_array($sql))
{
$target_path = "stampsforsale/" . basename($row['country'] . ".jpg");
echo ("<td><a href='" . $target_path . "' target='_blank'><img src='" . $target_path . "'width=150 height=100></a><br />" . $row['country'] . "<br />" . $row['description'] . "</br>" . $row['price'] . "<br /><br /></td>");
$count++;
if ($count % 3 == 0)
{
echo ("<tr>");
}
}
echo ("</tr></table>");
}
// end of displaying data
?>
The above code works fine and it loads inside a the main section on my web page as follows: index.php?mC=stampsforexchange.php.
In order not to get a huge number of results I am planning to put the above code inside a function and then set the stampforexchange.php page with flags for each country so that when a particular country is clicked only stamps from that country are shown. The following is the above code revised into a function.
<?php
include ("databaseconnections/conx_stampsforsale.php");
function getCountryStamps($country)
{
$sql = mysql_query("SELECT country, description, price FROM stampsforsale WHERE country = $country");
if (!$sql)
die ("Error Displaying Data. " . mysql_error());
else
{
echo ("<table><tr>");
$count = 0;
while ($row = mysql_fetch_array($sql))
{
$target_path = "stampsforsale/" . basename($row['country'] . ".jpg");
echo ("<td><a href='" . $target_path . "' target='_blank'><img src='" . $target_path . "'width=150 height=100></a><br />" . $row['country'] . "<br />" . $row['description'] . "</br>" . $row['price'] . "<br /><br /></td>");
$count++;
if ($count % 3 == 0)
{
echo ("<tr>");
}
}
echo ("</tr></table>");
}
// end of displaying data
}
?>
And this is the html part where I am trying to call the function:
<td><a href="index.php?mC=getCountryStamps(Malta)"><img src="flags/malta.gif" width=100px height="67px" /><br />Malta</td></a>
However I am getting the following warning message:
Warning: include(getCountryStamps(Malta)): failed to open stream: No such file or directory in C:\xampp\htdocs\stamps\index.php on line 21Warning: include(): Failed opening 'getCountryStamps(Malta)' for inclusion (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\stamps\index.php on line 21 Can someone please point in the right direction as I am stuck with this one? Thank you in advance. Hi,
I am using fancybox on my site and the function I am using to display the title and data-caption is this.
$(document).ready(function() {
$('.fancybox').fancybox({
beforeShow : function(){
this.title = this.title +"<br>" + $(this.element).data("caption");
}
});
}); // ready
I would like to change this so that I can add a hypertext link.
Here is what a sample of the HTML looks like:
<img src="img/portfolio/GSI_web.png" height="194" width="400" alt="Globalsoftwareinc.com" />
<h4>www.globalsoftwareinc.com</h4>
<div class="portfolio-desc align-center">
<div class="folio-info">
<h5><a title="globalsoftwareinc.com" href="#" title="www.globalsoftwareinc.com">Globalsoftwareinc.com</a></h5>
<a title="Global Software Inc. website" href="img/portfolio/GSI_web_large.png" class="fancybox" data-caption="I was the interactive web designer at Global Software, Inc. and assisted in the re-design and development of Global Software, Inc. in Drupal<br>www.globalsoftwareinc.com"><i class="fa fa-plus fa-2x"></i></a>
</div>
</div>
</div>
</article>
so for example I would want to make www.globalsoftwareinc a hyperlink and that isn't do-able currently. It breaks the code.
thanks in advance!
So a project I have simply to learn how it is done is to make an auto updating sitemap with a auto submitter. I have been doing a little research on sitemaps but haven't found much in the way of a tutorial or white paper or similar, anyway I was wondering if I am on the right track or not. What I was thinking for the auto-updating sitemap is since site maps are XML, when an article is published using my custom CMS/Blogging system, I make it rewrite the sitemap appending the new URL that will be generated. Then for the auto-submit, I can either make it a cron job or just manual press, but it would go though a for list of URLs, replacing the end part with my site map url. I think that is how it would be done. If you have a better idea, or can point out an article so I can understand a lot more with sitemaps, I will appreciate it, I am trying to learn as much as possible, I have gone to the offical website (sitemaps.org) but it doesn't have what I am looking for. Thanks, James

I'm having a problem with make my links work. I have a link saved in a session variable but when I print it to the screen it doesn't seem to work. What happens is instead of the link taking you to "www.google.com" it will but the currently directory first so for example if would be "www.example.com/folder/www.google.com". I have checked the page source and it appears to be fine so I'm not sure what's happening. I've copied my code below. echo("<h3 class=\"left\"><a href=\"" . $_SESSION['submit_content_link'] . "\" class=\"linker\" title=\"1\" target=\"_blank\">" . $_SESSION['submit_content_title'] . "</a></h3>"); Thanks for any help. I'm having a problem with including a list of clickable links. They keep including my website address before the web address instead of the the web address alone. Here is the code I'm using for it. The $item_url is the web address from the database. $content .="<table width=\"700\" height=\"50\" border=\"0\"><tr><td width=\"500\" class=\"titles\"><a href=$item_url target=\"_blank\">$item_title</a></td></tr><tr> <td width=\"400\" class=blackfont>Location: {$item_city}, {$item_state}</td></tr><tr><td class=blackfont>Country: {$item_country}</td></tr><br /> </table>"; if i put a link in to go to google say, <a href='www.google.com'>link1</a> it goes to www.mysite.co.uk/www.google.com can any1 help? cheers mat when i upload a link using the form below it adds \ into it like this <a href=\"http://www.google.co.uk\" target=\"_blank\">test</a> and the link is unusable with them any way to stop this <?php include("dbinfo.inc.php"); mysql_connect($localhost,$username,$password); @mysql_select_db($database) or die( "Unable to select database"); $query="SELECT * FROM News WHERE id='$id'"; $result=mysql_query($query); $num=mysql_numrows($result); mysql_close(); $i=0; while ($i < $num) { $News=mysql_result($result,$i,"News"); ?> <form action="updated.php"> <input type="hidden" name="ud_id" value="<? echo "$id"; ?>"> News:<br> <TEXTAREA NAME="ud_News" COLS=40 ROWS=6><? echo "$News"?></TEXTAREA><br> <input type="Submit" value="Update"> </form> <?php ++$i; } ?> I'm trying to figure out a way to incorporate multiple sorts on my php page. On the page of products, I want users to have three choices of links: one by date, one by price - low to high and one by price - high to low. I know how to perform ASC & DESC sorts in MySql but I'm not sure how to go about this sort with the three choices without creating more pages. I would really like it to stay with the same page. Is this even possible?? How would I go about it? Here is the section of code : $get_items_sql = mysql_query("SELECT id, thumb, username, sub_id, title, ROUND(price,2) AS price, date FROM product WHERE CURDATE() <= relist_date AND inactive IS NULL AND sold IS NULL AND cat_id = '1' ORDER BY date ") or die(mysql_error());; if (mysql_num_rows($get_items_sql) < 1) { $content = "<p><em>Sorry, no items in this category.</em></p>\n"; } else { $col = 0; $content .= "<ul>\n"; while ($items = mysql_fetch_array($get_items_sql)) { $item_url = "items3.php?id={$items['id']}&username={$items['username']}"; $item_title = stripslashes($items['title']); $item_price = $items['price']; $item_photo = $items['thumb']; $item_username = $items['username']; $item_date = $items['date']; $content .= ""; list($width) = getimagesize("image_files/{$item_photo}"); // set the maximum width of the image here $maxWidth = 100; if ($width > $maxWidth); $content .= "<table width=\"693\" border=\"0\" class=anotherfont><tr><td width=\"101\"> <a href=\"{$item_url}\"> <img alt=\"{$item_title}\" border=0 width=\"{$maxWidth}\" src=\"image_files/{$item_photo}\" /></a><td width=\"200\"> <a href=\"{$item_url}\">{$item_title}</a></td> <td width=\"109\">{$item_username}</td><td width=\"101\"> {$item_date}</td><td width=\"99\">\${$item_price} USD </td></tr></table>"; $content .= "\n"; Hi guys. Im not sure if this is normal in php. But if someone could help. Its much appreciated! I try to do an anchor link on another page, here is my example: <a name="testi"></a> //somewhere above the code below <a href='$targetpage?page=$prev#testi'>prev</a> //anchor link When i click on "prev" link, it direct me to another page correctly. But my page name/title which is: <title>Testimonials | Ten International</title> //page name appears to be Testimonials | Ten International#testi How do i actually make the word #testi in my page name/title disappear of hidden? Hi, This is a image tooltip from database. but I have got the problem, Not Working! How can i fix it. <a href="index.php?MD=urundetay&resimid=<?php echo $row_uruns['resimid']; ?>"><img src="urun_resim/<?php echo $row_image['image']; ?>" width="150" border="0" /></a> Hello, I am having a problem with a link text when ever there is a text that has multiple words. (e.g. 2 Cor prints out with the white space but when I click on the text the url is printed without the text as 2Cor and so it doesn't find a match) here is my code: Code: [Select] <?php if($_GET['book'] == ''){ $books = $wpdb->get_results(" SELECT book_name FROM {$wpdb->prefix}sb_books_sermons LEFT JOIN {$wpdb->prefix}sb_books ON {$wpdb->prefix}sb_books_sermons.book_name = name GROUP BY book_name ORDER BY {$wpdb->prefix}sb_books.id ASC "); foreach($books as $book){ echo '<li><div class="droidlist"><a href="bible/?book='.htmlentities($book->book_name).'">'.$book->book_name.'</a></div></li>'."\n\t"; } } On my website, I have links to another website. The problem is, when I clink on the link for the first time, the target website gives me the error "Your session has expired". Then I have two options: Close that window and click on the link again: this will load the page without any problem. Refresh the window with the error message, again page loads with no issues. This is not very convenient for my users. I wonder if there is any way to fix this problem from my end using some coding? Not sure how. Thanks in advance. Hi, I have one webhost (A) that supports no PHP and has unlimited bandwidth. I have a second webhost (B) that does support PHP, but has limited bandwidth. The website is on host A and contains a 5mb file that people can download and I'd like to count the downloads. But now I need to use host B to count the downloads. I'm using this small script on host B to count the downloads. <?php $hits=file("count.txt"); $hits[0]++;$fp=fopen("count.txt","w"); fputs($fp,$hits[0]); fclose($fp); header("Location: http://webhost-A.com/files/download.zip"); ?> The download link people see on my website is: http://webhost-B.com/download.php Generally this works fine, but I found out that people can still find the direct link with download managers and then put that direct link on their website, which prevents me from counting those downloads. A solution I found is to use ReadFile. But the problem is that when using ReadFile, host B first downloads the file from host A and then sends it to the user and that's exactly what I don't want. Is it possible to let people download the file directly from host A without showing the direct download link in any way and also count the downloads? Hey guys im having a problem with emailing a link using local host mail. I'm using out look express with Mercury. I shorten the email below as much as possible. Its really wierd the target for the link is correct but clicking on it gives me this res ieframe.dll res://ieframe.dll/syntax.htm#http//localhost/stargate/users/account_settings.php? npd=82b1e0df295ee681f1fa2f213ade823d $to = $_POST['resendemail']; $from = "stargate@localhost.com"; $subject = "Stargate System Lords Password Recovery"; $message = "<html> <body background=\"#4B4B4B\"> <h1>Stargate System Lords Password Recovery</h1> Dear ".$users1['name'].", <br> <center> <a href="localhost/stargate/users/account_settings.php?npd=$new_password ">Log In</a> <p> <br /> </font> </body> </html>"; $headers = "From: Stargate Game Password Recovery <stargate@localhost.com>\r\n"; $headers .= "Content-type: text/html\r\n"; mail($to, $subject, $message, $headers); I am having trouble getting a function to work. The function I am having trouble with is in a database.php include file that I am using successfully already. In this particular case I have had it read a function in the same file immediately before, with no problem. Here is the code. $database->addlog($username, $processname, "Can access database", 0); $prodidisused = $database->prodisused($prodid); and the error I am getting is Fatal error: Call to undefined method MySQLDB::prodisused() in /home/paulsinc/public_html/testcrm/create_product.php on line 217 The function which is in database.php is function prodisused($prodid) { $q = "SELECT * FROM orderitems WHERE productid = '$prodid'"; $result = mysql_query($q, $this->connection); /* Error occurred, return given name by default */ if (!$result || (mysql_numrows($result) < 1)) { return false; } /* Return result array */ return true; } As you can see, the function addlog which is also in database.php is working. Thanks for all suggestions. I have a function that needs to return a value and it isn’t.I think it’s a scope issue but can’t solve it. The function is
function is_connected()
{
$addr= 'www.google.com';
if (!$socket = @fsockopen($addr, 80, $num, $error, 5)){
$connection = 0;
}else {
$connection = 1;
{
return $connection;
}
is_connected() echo $connection; The function works, but I do get a warning $connection not defined and I don’t get a value. Any help appreciated. |
